[1.12 Merge]Hdf5 1 12 warnings fixes (#1715)

* Warnings fixes (#1680)

* Clean stack size warnings in sio_engine (#1687)

* Fixes stack size warnings in tcoords.c (#1688)

* Address some warnings from casting away of const (#1684)

* Fixes stack size warnings in ntypes (#1695)

* Fixes stack size warnings in dtransform (#1696)

* Fixes stack size warnings in set_extent test (#1698)

* Be a bit safer with signed arithmetic, thus quieting some signed-overflow warnings from GCC (#1706)

* Avoid a signed overflow: check the range of `entry_ptr->age` before
increasing it instead of increasing it and then checking the range.
This quiets a GCC warning.

* Avoid the potential for signed overflow by rewriting expressions
`MAX(0, fwidth - n)` as `MAX(n, fwidth) - n` for various `n`.
This change quiets some GCC warnings.

* Change some local variables that cannot take sensible negative values
from signed to unsigned.  This quiets GCC warnings about potential
signed overflow.

* In a handful of instances, check the range of a signed integer before
increasing/decreasing it, just in case the increase/decrease overflows.
This quiets a handful of GCC signed-overflow warnings.

* Committing clang-format changes

* Fix object size warnings in cache.c test (#1701)

* Fix some const cast and stack/static object size warnings (#1700)

* Fix various warnings

* Move HDfree_const to H5private.h for wider use

* Print output from all ranks in parallel tests on allocation failure

* Move const pointer freeing macro to h5test.h for now

* Stop lying about H5S_t const-ness (#1209)

Hyperslabs can be reworked inside several H5S callbacks, making H5S_t
non-const in some places where it is marked const. This change switches
these incorrectly const H5S_t pointer parameters and variables to
non-const where appropriate.

* Fix a few warnings after recent H5S const-related changes (#1225)

* Adjustments for HDF5 1.12
